Beginning in 1889, when morning prayers were changed to a daily 20-minute chapel service, the university had compulsory chapel attendance. By the 1920s, compulsory chapel programs were held weekly—in Science Hall, then in (new) Jefferson Hall, and then in Alumni Memorial Gymnasium. In 1936 the All Students’ Club and the administration worked out a new assigned-seat arrangement to combat complaints that students had to sit next to an unknown seat neighbor in chapel. In the new arrangement, students were seated by their counties (or states) of origin. In 1940–41 the university made chapel attendance voluntary (although graduate students had been excused from compulsory attendance by 1930). The weekly, voluntary Student Assembly continued until the enrollment declines of 1943 and 1944. Following World War II, special assemblies were held from time to time, but regularly scheduled assemblies were not reinstituted.
